Field Emission Simulations of Carbon Nanotubes and Graphene with an Atomic Model

Most models of field emission from carbon nanotubes (CNTs) and graphene sheets consider the geometry of the emitter tip as a smooth spherical surface. In these models, indicated with the terms simplified geometry (SG), the electronic distribution is not taken into account. However, the electronic distribution is concentrated around the atoms nuclei and their bonds forming hexagonal patterns that affect the field enhancement and largely determines the field view more»
